A higher than stock stall speed as delivered by the Holeshot converter will provide several advantages and benefits in vehicles with modified engines. Many modifications, particularly big cams, tend to reduce low end power and torque. The high stall converter allows the engine to launch the car at higher rpm where more torque is available.

The Holeshot is generally a very good choice for the typical street machine that is looking for better launch capability and more strength. Street rods with modified engines will also benefit from a Holeshot converter. Features a 10.5" bolt circle and a 24-spline input shaft.

Stall speed listings are based on engines producing 230lb. ft. of torque at 2,500RPM. More torque at 2,500RPM will give you more stall speed, less torque at 2,500RPM will give you less stall speed than the stall speed ratings indicated.

66 mustang, C4 trans . with 10-1/2 bp. 289 engine being bored out 30 over , new cam etc. I want a higher stall speed than stock so is 2400 rpm too high for this engine ? Do I need to wait until it gets put on the dyno to see how much torque?

Choosing a convertor all depends on what you are going to do with the car, street driving, drag racing etc.

I have a stock 200, but the local shop feels the shaking at stop lights is due to the torque converter not working right. Is this possible and would this be the best choice fr a stock motor and trans?

Asked by: Shan66

Without seeing it, we can say it's possible, but that's about it. Not knowing anything about it (engine, trans, etc), too, we can only say that this torque converter might be a good replacement.
